I have been reading HG/SS for about 4 years. My early favorites include Master of Enchantment, Prophecy's Pawns, Forget Me Not and You Can't Have One Without the Other. Currently I am anxiously following 3 WIPs - The Self-Writing Parchment, Bride of the Potions Professor, and A Walk Through the Fire.

Granger/Snape, HG/SS, or Potions & Ink Spots. No matter what you call it.
